OVERVIEW
The 3Com® Router 3000 series routers provide the following types of interfaces:
■Ethernet interface
■Synchronous/asynchronous serial interface
■Auxiliary (AUX) port
■ISDN BRI S/T and U port
■CT1/PRI port
These features allow you to combine the various technologies, such as PSTN/ISDN,
FR (Frame Relay), X.25, leased line, and T1 line, for networking. These multiple
interfaces also allow Router 3000 series routers to interoperate with the products
of other manufacturers on all levels.
Router 3000 routers use three types of memory:
■Synchronous Dynamic Random Access Memory (SDRAM) — Saves router
operation system software
■Flash memory — Saves router program files, configuration files and so on
■Boot ROM — Saves boot and initialization programs of the router

PREPARING TO INSTALL THE OUTER R
Safety Warnings As you prepare to install your router, consider the following safety guidelines:
■Switch off the power supply before connecting the cables.
■Keep the router far away from any heat source.
■To ensure normal heat dissipation, do not stack routers during the installation.
■Do not keep a router in a damp place, and prevent liquid from getting into the
router.
■Make sure that the neutral point of the power is grounded properly, to avoid
personal injury.
■Make sure that the power is off before plugging or unplugging the interface
cards, modules and cables of the router.
■Before removing the chassis, disconnect all the power cords and external
cables.
■To avoid damage to the router, connect all the cables correctly, and never
connect telephone cables (including the ISDN lines) to the console or AUX port.
■During the installation, wear the ESD (Electro-Static Discharge) preventive wrist
strap and ESD-preventive gloves. See the Static Electricity section in this chapter
for additional information on ESD prevention.
■3Com recommends that you use an uninterrupted power supply (UPS) with
your router.
■To enhance the anti-lightning-strike capability of the router, install a power
arrester at the front end of the power input, and a special arrester at the input
end of the outdoor cable, such as telephone cable, ISDN line or T1/E1 line.
General Site
Requirements
The environment of the installation site influences the performance and lifetime of
the router. In addition, if the router operates in inappropriate working
environment, its performance will become unreliable. The installation site for your
router should meet the following requirements for temperature and humidity,
dust, gases, static electricity, and electromagnetic discharge.
Temperature and
Humidity
To ensure normal operation and to prolong the operational lifetime of the router,
the equipment room must maintain adequate temperature and humidity. If the
equipment room is damp, it is likely to affect the performance of the insulating
material, which may result in electric leakage and lead to metal erosion.
If the equipment room is very dry, the insulating shim will contract, leading to
loosening of the fastening screws. In addition, static electricity will be produced,
which damages the complementary metal-oxide-semiconductor (CMOS) circuit on
20 C HAPTER 2: PREPARING TO INSTALL THE ROUTER
the router. If the equipment is always very hot, the aging process of insulating
materials accelerates, which affects the reliability of the router and even its
operational lifetime. The requirements for the temperature and humidity of the
router installation site are listed in Table 1.
Table 1 Temperature and Humidity Requirements
Dust Dust is harmful to the safe operation of the router. Dust on the chassis can result
in static absorption and cause faulty contact between metal connection
components or points. Especially when indoor humidity is low, dust is absorbed
more easily which not only shortens the operational lifetime of the equipment, but
also can result in communication failure. The specifications for the dust content
and diameter of the granule within the equipment room are listed in Table 2.
Table 2 Specification for Dust Content
Gases Besides the dust specification, the equipment room should also meet strict
requirements for the content of salt, acid and sulfide. These harmful gases can
accelerate the metal erosion and the aging process of some parts. The presence of
harmful gases, such as SO 2, H2S, NO2, NH3, and Cl 2, should be prevented. The
specific limitation values of these harmful gases are given in Table 3.
Table 3 Harmful Gas Limitation Values in Equipment Room
Static Electricity Although careful considerations in preventing electrostatic discharge (ESD) have
been taken in the design of the router, if the level of static electricity exceeds a
certain threshold, it will cause great damage to the circuit and even to the entire
router.
On the communication network connected to the router, the electrostatic
induction comes mainly from two aspects: one is from the outside electrical fields,
such as the outdoor high-voltage power cable and lightning, and the other is from
the inside system, such as indoor environment, floor material and the system
structure.

Workbench
Requirements
Whether you install the router in a cabinet or directly place it on the workbench, it
is necessary to ensure that:
■There is spacing reserved at the air inlet and outlet in the router so as to
facilitate the ventilation of the router cabinet.
■The cabinet and workbench are firm enough to support the weight of the
router and other installation accessories.
■The cabinet and workbench are well grounded.
Inspecting the Router
and Accessories
After you verify that the installation conditions comply with these requirements,
open the packing case of the router and check the contents against the your order
contract. Contact your Service representative if you find any discrepancies.
Installation Equipment To install your router, you will need:
■Tools
Phillips screwdriver
Flat-head screwdriver
ESD-preventive wrist strap and ESD-preventive gloves
Flat-blade screws (used in wall mounting)
■Cables
Ethernet cable
Console cable
AUX cable
Power supply, power cord, and chassis ground wire
Interface cables for the selected interface modules
■Equipment
A router
Ethernet 10/100Base-T Hub or LAN switch
Channel service unit/data service unit (CSU/DSU) or other data communications
equipment (DCE) equipment (such as a modem)
Configuration terminal, such as a PC
Additional equipment for the selected interface modules

Figure 2 Hanging the Router on a Vertical Surface
Installing the Router
on a Workbench
To install the router on a workbench, take the following precautions:
■Make sure that the workbench is smooth and stable.
■Leave a heat-dissipation clearance of 10cm (4in) around the router.
■Do not put heavy things on the router.
Connecting the
Protection Ground
Wire
Properly connect the protection ground (PGND) wire before connecting other
cables. Shorten the ground wire as much as possible to avoid the router and the
peer device being damaged during lightning.
The AC input of the router is connected to an AC noise filter whose neutral point
is connected to the chassis directly, that is PGND (protection ground). The chassis
must be grounded properly, to improve the router’s ability to resist electromagnetic
interference. The PGND also provides protection for the external network, to
ensure that the PGND wire lets out the lightning current.
The grounding point of the chassis is located on the rear panel and is labeled with
a grounding label. The grounding resistance should not be greater than 5 ohm.
Connect this point to the ground using a grounding wire.
Connecting the Power
Cable
External AC power supplies are provided for Router 3000 series routers. The
power supplies have the following specifications:
■Input: 100 to 240VAC, 50/60Hz, 0.5 to 1 A
■Output: 12VDC, 4A
Connect the power supply to a 3-core outlet with a neutral point. The neutral
point of the outlet should be grounded reliably.
To connect the power supply:
1Turn off the power to the router.
2Connect the output end of the power supply to the power socket on the rear
panel of the router.
3Connect the input end of the power supply to the AC power outlet.
4Turn on the power switch on the router.
5Confirm that the router has power by checking whether the POWER LED is on.
Pan-head screw

2Connect the output of the power supply to the power input on the rear panel of
the router.
3Insert the input connector of the power supply into an AC power outlet.
4Turn on the power the power to the router.
5Confirm that the router has power by checking whether the POWER LED is on.
6If you repeat this procedure several times and the POWER LED remains off, see
Chapter 6, Troubleshooting.
Connecting the Router
to the Console
Terminal
The Router 3000 series routers provide an EIA/TIA-232 asynchronous serial console
port, through which you can configure the router.
The console cable is an 8-core shielded cable. The end that is used to connect to
the console port of the router has an RJ-45 connector. The other end of the
console cable has both a DB-9 (female) adapter and a DB-25 (female) adapter. Use
the appropriate connector for the port on the console terminal.
Figure 4 illustrates the console cable.

Connecting the Router
to the Ethernet
The Router 3000 series routers provide a fixed 10/100BASE-TX fast Ethernet
interface that uses category-5 twisted pair cable, as shown in Figure 5
Figure 5 Ethernet Cable Assembly
The Ethernet cables are classified as straight-through network cable and crossover
network cable. They have the following features:
■Straight-through network cable — The sequences of the wires crimped at the
RJ-45 connectors of the two ends are the same. The cable is used in the
connection between a terminal device, such as a PC or a router, and the Hub or
LAN Switch. Straight-through network cables are delivered along with the
router.
■Crossover network cable — The sequences of the wires crimped at the RJ-45
connectors of the two ends are different. The cable is used in the connection
between the terminal device, such as a PC or a router, and another terminal
device. You can create this cable yourself, if necessary.
For the pinouts, identification and making of the two network cables, see
Appendix A. Take the following considerations into account before you connect:
■The fixed Ethernet cables are included in the standard configuration of the
router.
■Use shielded cables to ensure electromagnetic compatibility.
■Identify the mark on the module port so you can plug the cable in correctly.
■When connecting the Ethernet cable to a LAN Switch, plug the cable into the
10/100BASE-T interface marked with MDIX.
To connect the Ethernet cable:
1Turn off power to the router.
2Select the Ethernet cable.
When connecting the router with a PC or a router, use the crossover network
cable.
Connecting the Router to the WAN 27
When connecting the router to a hub or a LAN switch, use the straight-through
network cable.
3Connect one end of the Ethernet cable to the appropriate Ethernet module on the
router.
4Connect the other end of the Ethernet cable to the Ethernet interface of the Hub
or the LAN switch.
5Verify the connection by checking that the 100M ETH LED on the top of the router
is on.
Connecting the Router
to the WAN
The Router 3000 series routers provide the following WAN interfaces:
■AUX port (all models)
■Mutiprotocol synchronous/asynchronous serial port (Router 3012, Router
3013, Router 3015)
■ISDN S/T (Router 3013)
■ISDN U (Router 3015)
■CT1/PRI ( Router 3016)
Connecting the AUX
Port to the Modem
The auxiliary (AUX) port is an EIA/TIA-232-compliant sync/async serial interface
that is used for remote configuration or dial-up backup. To be connected to a
remote device, a local modem must be connected to a remote modem through
PSTN. For the connection method, see Chapter 4, Booting and Configuring the
Router. If the console port fails, the AUX port can also serve as a console port. For
AUX port specifications, see Chapter 1, Overview.
The AUX cable is an 8-core shielded cable. One end of the cable has an RJ-45
connector and connects to the AUX port of the router. The other end has both a
DB-25 (male) adapter and a DB-9 (male) adapter. Use the appropriate connector
for the port on the modem.

analog modem.
For pinout details of the AUX cable, see Appendix A.
Connecting the
Synchronous/
Asynchronous Serial
Interface to a CSU/DSU
The synchronous/asynchronous serial interface is usually used to connect a WAN
device, such as a modem, and a CSU/DSU. It can operate in
synchronous/asynchronous mode and DTE/DCE mode. For the attributes of the
interface, see Chapter 1 ., Overview
Synchronous and Asynchronous mode
V.35 and V.24 (EIA/TIA-232) standards support synchronous operating mode,
while only V.24 (EIA/TIA-232) standard supports the asynchronous operating
mode. The maximum transmission distance and baud rate of the signal vary with
the operating mode. See Table 1 for the details.
Table 1 Transmission Rate and Transmission Distance of V.24 (EIA/TIA-232)/V.35 Cable
Caution: The baud rate should not exceed 64 Kbps when the V.24 cable operates
in synchronous mode.
DTE and DCE mode
The synchronous serial interface can operate in both DTE mode and DCE mode.
For two devices connected directly, one device should operate in DTE mode, and
the other device should operate in DCE mode. The DCE mode device provides a
synchronous clock and specifies the transmission rate, the DTE mode device
accepts the synchronous clock and communicates at the specified transmission
rate. Usually, the router serves as the DTE device. To determine whether the device
is a DTE or a DCE, refer to the user manual for the device. Table 2 helps identify
DTE and DCE devices.

Connecting the Router to the WAN 29
In general, the asynchronous serial interface is connected to a modem or a
terminal adapter (TA) to act as the dial-up interface. In this case, it is unnecessary
to determine whether the device is DTE or DCE, you must only select the
appropriate baud rate.
The synchronous/asynchronous serial interface cable is connected to a DB-50
receptacle. Proper connection cable needs to be selected for the protocol applied.
Nine types of synchronous/asynchronous serial interface cables are available.
However, these cables are optional and you must select the proper one based on
your requirements when you purchase the router All these types of cables have a
DB-50 adapter at the router end.
At the network end, the connector is different for each type of cable, as described
in the following list:
■V.24 (EIA/TIA-232) DTE cable — DB-25 (male) adapter
■V.24 (EIA/TIA-232) DCE cable — DB-25 (female) adapter
■V.35 DTE cable — 34-pin (male) adapter
■V.35 DCE cable — 34-pin (female) adapter
■X.21 DTE cable — DB15 (male) adapter
■X.21 DCE cable — DB15 (female) adapter
■EIA/TIA-449 DTE cable — DB37 (male) adapter
■EIA/TIA-449 DCE cable — DB37 (female) adapter
■EIA-530 DTE cable — DB25 (male) adapter
For the pinouts of these cables, see Appendix A.

The configuration process includes the following steps:
1Clarify your networking requirements. These requirements include:
■The connectivity requirements of the remote sites
■The types of LAN and WAN interfaces required for the network
■The configuration of IP and IP subnet settings and any other protocols
■The network reliability, management, and security policies
2Based on your network requirements, draw a clear and integrated networking
diagram.
Configuration Fundamentals of the Router 41
3Configure the WAN interface of the router:
■Configure the physical operating parameters (the operating mode of the serial
interface, baud rate, and synchronous clock) of the interface according to the
transmission medium of the WAN. For the dial-up interface, you need to
configure DDR parameters.
■Configure the link layer protocol encapsulated on the interface and the related
operating parameters according to the type of the WAN.
4Configure the IP addresses or IPX network number for all the ports of the router
according to the division of the subnets.
5Configure the routes. If you have to start up the dynamic routing protocol,
configure the related operating parameters of the protocol.
6Create the security configuration for the router, as necessary.
7Create the reliability configuration for the router, as necessary.
SNMP Management For help managing routers on your network, you can use 3Com Network
Supervisor software to discover, map, and display network links and IP devices.
To allow Network Supervisor to monitor your routers, you must first configure
SNMP V1 and SNMP Trap support with the following commands:
[3Com] snmp-agent sys-info version v1
[3Com] snmp-agent community read <read-community-string>
[3Com] snmp-agent community write <write-community-string>
[3Com] snmp-agent trap enable
[3Com] snmp-agent target-host trap address <addr> parameter
v1 securityname <security-name-string>
In this example, <addr> is the address of the PC on which you have installed Network
Supervisor.
To learn more about Network Supervisor, on the 3Com Corporation World Wide
Web site, enter this URL into your Internet browser:
http://www.3com.com/3ns
Command Line Interface The command line interface of the Router 3000 series routers provides commands
to configure and manage the router. The command line interface has the
following characteristics:
■Performs the local configuration through the console port.
■Performs local or remote configuration through the telnet command, which
can be used to log on directly and manage other routers.
■Implements the configuration on the router through the terminals (the
asynchronous interface, including those connected to the AUX port and AS
port) in the dumb terminal mode.
■Configures the hierarchical user protection (guest, operator, administrator).
Only administrator users are authorized to configure and manage the routers.
■Online help, available by typing ? at any time.
42 C HAPTER 4: BOOTING AND CONFIGURING THE ROUTER
■Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose
the availability of the network.
■Provides detailed debugging information to diagnose network faults.
■The command line interpreter adopts fuzzy search for the keywords of the
command. A conflict-free keyword if entered, will be interpreted accordingly.
For example, for a display command, you can enter dis.
To facilitate the management of the router in the system view, all the commands
are grouped. Each group corresponds to a view. Users can use these commands to
switch between different views. Many commands are limited to use in a single
view. Other commands (such as ping, display current-configuration, interface)
can be executed in all views.

Uploading and
Downloading
Applications and
Configuration Files
Using FTP
Uploading files involves transferring them from a PC running the FTP client to a
router running the FTP server, through the router’s Ethernet interface. This is called
a put operation.
Downloading files involves transferring them from the FTP server on the router,
through its Ethernet port, to the PC running the FTP client. This is called a get
operation. All FTP clients, including local and remote users, who are connected to
a router can upload and download if they pass user authentication.
To transfer files using FTP, you must create the appropriate configuration, as shown
in Figure Figure 5 and 6, and described in the following procedures.
Figure 5 Creating a Local FTP Upload/Download Configuration
To create a local FTP upload/download configuration:
1Connect the PC to any of the Ethernet ports on the router.
2Configure the IP address for the Ethernet port on the router. The default IP address
is 10.110.10.10.
3Configure the IP address of the Ethernet port on the PC. The default IP address is
10.110.10.13.
The IP addresses of the PC network port and of the router’s Ethernet port must be
on the same segment.
4Copy the application program files to a path, the default is C:\version.
Figure 6 Creating a Remote FTP Upload/Download Configuration
To create a remote FTP upload/download configuration:
1Connect the PC to any port on the router through a WAN. This procedure does
not require that the IP address of the PC and that of the router be on the same
segment and is used for remote upgrading routers.
2Copy the application program files or configuration files to a path, the default is
C:\version.

Maintaining Router
Hardware
In preparation for the maintenance of your router hardware, collect and have
ready the following tools:
■Phillips screwdriver
■ESD-preventive wrist strap and ESD-preventive glove
■Static shielding bag
■Chip extractor
Caution: Observe the following precautions when maintaining your router
hardware:
■There is a seal on one of the screws on the chassis of the Router 3000 routers.
When the Service representative performs maintenance on the router, the seal
is must be intact. Contact your Service representative before you open the
chassis.
■Replace the hardware of router sensibly and in a proper way under the
guidance of the technical support personnel.
■Confirm that all power supplies have been disconnected from the router while
performing the hardware maintenance. Otherwise, the operator may get
injured through an electric shock.
■Wear an ESD-preventive wrist strap and ESD-preventive gloves during the
hardware maintenance for the router and ensure that the strap makes a good
skin contact.
■For the device to operate normally, use only the SDRAM provided by 3Com
Corporation.
Opening the Cover of
Router Chassis
Use the following procedure to open the router chassis cover:
1Turn off the power to router and remove the power cord.
2Remove all port cables on the back panel of the router. Do not remove the PGND
cable.
3Place the router upside down on your work surface. Remove the screws on the
bottom of the chassis with the Phillips screwdriver and set them aside.
4Turn the router right side up, with the rear panel toward you.
5Remove the captive screws on the rear panel with the Phillips screwdriver and set
them aside.
6Raise the chassis cover until it is free of the bottom of the router, and put it to one
side.

Replacing the Boot ROM When a Boot ROM is damaged or when data that becomes corrupted because of
a software failure and cannot be corrected, it should be replaced.
Router 3000 Boot ROMs are located at the same position on the mainboard, as
shown in .
Figure 8 Boot ROM Location
Caution: Use a chip extractor to replace the Boot ROM.
To replace the Boot ROM:
1Insert the top end of the chip extractor into the Boot ROM socket, turn inward
slightly, withdraw the extractor upward and lift the Boot ROM out.
2Put the Boot ROM into the static shielding bag.
3Insert the end of the chip extractor into the socket of the new Boot ROM.
4Position the Boot ROM so that the beveled edge of the socket matches the
beveled edge on the Boot ROM and plug it into the Boot ROM socket.
Caution: Be careful not to damage or bend the pins at the bottom of the Boot
ROM. If the pins are bent, straighten them with needle-nose pliers.

TROUBLESHOOTING
The Power LED is Off. If the power LED is off, verify that:
■The power switch of the router is turned on.
■The power supply switch is turned on.
■The power cord of the router is connected properly.
■The power supply suits the requirement of the router.
Caution: Do not plug in or unplug the power cord when the power is on. After
having checked the conditions in the previous list, if the power LED is still off,
contact your Service representative.
Nothing is Displayed
on the Terminal after
Power-On
After the system runs the power-on self-test (POST), if the system operates
normally, the start-up information is displayed on the console terminal. If the
configuration system has a fault, the terminal may display nothing.
If the terminal does not display any information after the power-on self-test, verify
that:
■The power system is normal.
■The console cable is connected correctly.
If the power system is normal and the console cable is connected properly, there
may be something wrong with the console cable or the HyperTerminal
parameters. Check the cable or the parameters.
HyperTerminal parameters should have the following values:
■Baud — 9600
■Data bits — 8
■Stop bit — 1
■Parity — None
■Flow control — None
■Terminal emulation — VT100
If the parameter settings do not match these values, reconfigure them.
If the previous checks do not solve the problem, contact your Service
representative and follow the representative’s instructions.
56 CHAPTER 6: TROUBLESHOOTING
Illegible Characters
Display on the
Terminal after
Power-On
If the system operates normally after the system runs the power-on self-test
(POST), the start-up information is displayed on the console terminal. If the
configuration system has a fault, the terminal may display only illegible characters.
If the console terminal displays illegible characters after the POST, verify that the
HyperTerminal parameters are set properly, as follows:
■Baud: 9600
■Data bits: 8
■Stop bit: 1
■Parity: None
■Flow control: None
■Terminal emulation: VT100
If the parameter settings do not match these values, reconfigure them.
